Direct answer
On CP Plus families that document the Dahua-style realmonitor path, channel numbers start at 1. subtype=0 is the main stream and subtype=1 is the sub stream.
Port 554 is the documented default on current CP Plus recorder manuals. If your device uses another port or path, use the value shown in its network settings or manual.
2026 compatibility examples
CP Plus publishes protocol support by model, so check the exact product rather than relying only on the brand name.
| CP Plus product | Published local integration | What to verify |
|---|---|---|
| CP-UNC-TS41PL3 IP camera | RTSP; ONVIF Profiles S and G | Firmware, stream codec and configured credentials |
| CP-UNR-108F1 NVR | RTSP; ONVIF Profiles T, S and G | Logical channel, recorder account and RTSP port |
| CP-UNR-4K4162-V3 NVR | Third-party access through ONVIF and RTSP | Camera registration status and channel mapping |
| Other CP Plus camera/DVR/NVR | Model-dependent | Exact product page and current user manual |
Camera stream or recorder channel?
| Connection | Use this endpoint | Credentials | Channel |
|---|---|---|---|
| Direct IP camera | Camera IP and its RTSP port | Camera account | Usually 1 for a single sensor |
| Through CP Plus NVR/DVR | Recorder IP and its RTSP port | Recorder account | Logical channel shown in Camera Management |
This example requests channel 4's sub stream from the recorder. Do not assume that a physical PoE socket number always matches the logical channel after cameras are reordered.
Add a CP Plus camera through ONVIF
- Find the camera or recorder IP with the CPPLUS_IP Finder utility or your router's client list.
- Confirm that the exact model lists ONVIF and that ONVIF access is enabled if its firmware provides a switch.
- Keep the Apple device on the same LAN or VLAN for discovery.
- In SmartRTSP, scan for ONVIF cameras and select the device.
- Enter the device account, select a media profile and test the sub stream first.
For a CP Plus NVR, the current manual places remote camera registration under Main Menu > CAMERA > Add IP Camera. Choose ONVIF when adding a compatible third-party camera. Camera-side menus differ across product families, so use the exact camera manual for any ONVIF account or enable switch.
View CP Plus in SmartRTSP
SmartRTSP is an RTSP and ONVIF camera viewer for iPhone, iPad, Mac and Apple TV. Add a discovered ONVIF profile or paste one exact RTSP URL for each camera or recorder channel.
- Use sub streams for grids and switch to the main stream for detail.
- View up to eight cameras simultaneously on iPhone, iPad and Mac.
- Apple TV Monitor offers 4-, 6- or 9-tile layouts.
Troubleshooting by symptom
| Symptom | Likely cause | What to do |
|---|---|---|
| Camera does not appear in ONVIF scan | Different VLAN, Wi-Fi isolation, ONVIF disabled or unsupported model | Test on the same LAN, check the exact model specification, then add by IP or RTSP URL. |
| 401 Unauthorized | Wrong account for the endpoint | Use the recorder account for an NVR IP and the camera account for a direct camera IP. |
| Sub stream works but main is black | H.265, resolution, bitrate or decoder load | Test H.264, lower the main-stream load or continue with subtype 1. |
| Wrong camera appears | Recorder channel mapping changed | Read the current logical channel in Camera Management and update the URL. |
| Timeout on both streams | Wrong IP/port or network isolation | Confirm local reachability and the configured RTSP port; do not assume 554 after a port change. |
Security
Create a dedicated viewer account where the device supports one. Do not expose RTSP, ONVIF or the recorder web interface directly to the public internet. For remote viewing, connect to the camera network through a VPN.
Frequently asked questions
What is the CP Plus RTSP URL?
Try the documented realmonitor format with channel=1&subtype=0 for main or subtype=1 for sub stream, then confirm the exact model manual.
Does every CP Plus camera support ONVIF?
No. Many current products publish ONVIF profiles, but the supported profiles and setup steps are model-specific.
Can SmartRTSP show CP Plus NVR channels?
Yes, when the recorder exposes a compatible RTSP or ONVIF stream. Use the NVR IP, recorder credentials and the logical channel number.
